Disconnect the cable from the negative battery terminal. If the stereo in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. Using a large syringe or suction gun, suck as much fluid out of the power steering fluid reservoir as possible. Place a drain pan under the vehicle to catch any fluid that spills out when the hoses are disconnected. Loosen the right front wheel lug nuts, raise the vehicle and support it securely on jackstands. Remove the right front wheel. Remove the right front fender apron seal. Loosen the clamp and disconnect the fluid return hose from the pump. Remove the pressure line-to-pump union bolt and separate the line from the pump. Remove the sealing washers on each side of the fitting - these should be replaced when installing the pump. Loosen the adjuster and pivot bolts and remove the drivebelt. Remove the pivot, adjuster and any other mounting bolts, and remove the pump. Installation is the reverse of removal. Be sure to tighten the fluid line banjo bolt and the adjuster and pivot bolts to the torque. Adjust the drivebelt tension. Top up the fluid level in the reservoir and bleed the system.
